摘　　要：为了提高电动汽车制动过程中回收的制动能量,提出一种非线性规划控制的电动汽车制动能量回收的最优化控制策略。以某前驱型电动汽车为研究对象,通过对电动汽车制动过程的分析,采用实验数据与数学模型结合的方法,在Matlab/Simulink环境下搭建所设计的再生制动控制策略的系统仿真模型,并进行仿真验证分析。仿真结果表明,提出的控制策略能更好地实现能量的回收利用,验证了控制策略的有效性,为电动汽车制动能量回收系统的开发提供参考依据。In order to improve the braking energy recovered during the braking process of electric vehicle, an optimal control strategy of non linear programming control of electric vehicle brake energy recovery is proposed. A precursor of electric ve- hicle is used as a research object, through the analysis of the braking process of electric vehicle, the system simulation model of regenerative braking control strategy is designed in Matlab / Simulink environment by the combination of the experimental data and the mathematical model, the simulation analysis and verification are also carried out. The simulation results show that the proposed control strategy can better realize the energy recovery and verify the effectiveness of the control strategy, which can provide reference for the development of electric vehicle brake energy recovery system.
